788264 divided by 78 
The aim is to understand the frequency of 78 in 788264.

On to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 78

Going ahead to step 2:
When dividing 78 by 78, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 78 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 78

Advancing to step 3:
If we divide 8 by 78, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 78

Step 4:
The number 78 fits into 82 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 101.0
If we take 78 away from 82, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 78

Going ahead to step 5:
78 can be fit into 46 0 times, resulting in a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 1010.0
If we subtract 0 from 46, we get 46.
Bring next digit (4) of the dividend behind the 46 and repeat the process: 464 / 78

Going ahead to step 6:
78 can be fit into 464 5 times, resulting in a remainder of 74.
The next digit of our result is 5. 
Result so far: 10105.0
If we subtract 390 from 464, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
78 can be fit into 740 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 10105.9
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
380 divided by 78 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 10105.94
Subtract 312 from 380 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
When dividing 680 by 78, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 10105.948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
560 divided by 78 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 10105.9487
The remainder is 14 after subtracting 546 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
When dividing 140 by 78, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 10105.94871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 10105.948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
If we divide 740 by 78, we get 9 and a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 10105.9487179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
When dividing 380 by 78, we get 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 10105.94871794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 10105.94871794 with a remainder of 6.8e-08.
